A Non-Rigid Registration Method For Analyzing Myocardial Wall Motion For Cardiac Ct Images, Elizabeth B. Philps
A Non-Rigid Registration Method For Analyzing Myocardial Wall Motion For Cardiac Ct Images, Elizabeth B. Philps
Master's Theses (2009 -)
Cardiac resynchronization therapy (CRT) has a high percentage of non-responders. Successfully locating the optimal location for CRT lead placement on a priori images can increase efficiency in procedural preparation and execution and could potentially increase the rate of CRT responders.
Registration has been used in the past to assess the motion of medical images. Specifically, one method of non-rigid registration has been utilized to assess the motion of left ventricular MR cardiac images. As CT imaging is often performed as part of resynchronization treatment planning and is a fast and accessible means of imaging, extending this registration method to assessing …
Development Of A Velocity Metric For Rigid-Body Planar Motion, Luis Ernesto Criales Escobar
Development Of A Velocity Metric For Rigid-Body Planar Motion, Luis Ernesto Criales Escobar
Master's Theses (2009 -)
Two motions of motion quality have been developed for planar motion. They are the "best motion measure" and the "velocity metric". The "best motion measure" identifies the best motion for a given displacement. The "velocity metric" quantifies the discrepancy between two planar motions for the same rigid body.
The best motion measure compares the motion of each particle on the body to an "ideal", but usually unobtainable, motion. This ideal motion moves each particle from its current position to its desired position on a straight-line path. Although the ideal motion is not a valid rigid body motion, this does not …
